The US Congress, which began its 119th session, set an anti-record for the number of Christians among its members. There were fewer of them, less in the previous session (2023–2025), which continues the ten-fold trend of incremental decline. At the 2025–2027 session of the Congress, Christians will become 87% of the voting members of the Senate and the House of Representatives, simultaneously united. Less than 88% in the first session and 92% ten years ago.
The Congress will have 461 Christians, up from 469 at the front and 491 during the 2015–2017 session. This is the smallest number of Christians from the hours of the session of the Congress 2009–2011.
In fact, 87% of Christians are still a significant majority in Congress, which is significantly ahead of the majority of the adult population in the United States, which is on par with 62% after several decades of decline. In 2007, 78% of adult Americans were Christians, according to the Pew Research Center's religious landscape survey, and by the early 1960s, over 90% of adult Americans were Christians.
